Advanced acquisition and reconstruction methods have been proposed to improve spatial and temporal resolution for prone breast DCE. However, limited work has been performed in the supine setting, which is used in most downstream clinical services including surgery and biopsy. In this work, we propose a radial acquisition combined with self-gating and MOCCO reconstruction. We assess performance of these methods using a simulated breast phantom with respiratory motion and contrast kinetics allowing evaluation of reconstruction accuracy against the assigned ground truth. Evaluation of both spatial and temporal quality was also performed in a first in-vivo patient volunteer.
